Look at the "Reception" area of the wiki post for one of the Amiga's famous early games, Defender of the Crown. It's a quite from Brian Bagnal's Commodore book that explains to a degree the significance of experiencing the Amiga's graphics way back when. I remember the feeling he describes, well.

Also, I saw this article pop up yesterday that takes a look at "The Amiga Concsiousness." It may help, here.
